HBR 62%

HBR 62% is used as a bromine source in a variety of chemical syntheses for high-level applications, including pharma applications, fragrances and flavors. A strong acid in an aqueous solution, HBR 62% can also be used as a hydrobromination agent in a broad range of organic processes (for pharma and agro applications).

Packaging: Hydrobromic acid is supplied in the following packaging:

  • Drums
  • Intermediate Bulk Containers – IBCs
  • Bulk Truck Loads

Flammability and Exclusivity: Hydrobromic acid is non-flammable and non-explosive. At high temperature it will release toxic fumes of hydrogen bromide.

Toxicity: LD50 (inhalation rate): HBr 100% 2,858 ppm/1h. Hydrobromic acid is corrosive to eyes, skin and mucous membranes. Actual inhalation may produce delayed pulmonary edema. Direct contact results in serious corneal and skin burns.

Storage & Handling: Keep containers tightly closed and protected from physical damage. Use fluorinated vinyl chloride resins or polyethylene glass-coated equipment. Avoid breathing vapors and any other bodily contact.

Store in a dry, cool, well-ventilated area, away from incompatible materials.
